The Oscar winner is keeping details of what the line, which she'll debut on Monday (12Sep16), under wraps.

High-end clothing has been available for purchase on the Goop website for years, but items have never exclusively been designed and created solely by the brand's design team. Last year (Dec15), Goop chiefs teamed up with Valentino for a themed capsule collection, called Wonder Woman Valentino, and prior to that, they worked with Paltrow's good friend Stella MCCartney for an exclusive line as well.

Paltrow's latest venture into apparel comes weeks after it was announced she and her business partners are expanding the company and moving its creative operations from New York to America's West Coast, thanks to an injection of $10 million (£7.5 million) in funding.

The Iron Man star launched her digital newsletter in 2008 to share tips, tricks, and advice on everything from food, health, beauty, fashion, and sex. Since then, Goop has evolved into a lifestyle empire, but Paltrow recently admitted she is planning on reducing her involvement with the company, in hopes her partners can continue the success without her at the helm.

"More and more I would like it to be its own brand," she said at the 2016 Sage Summit business convention in July (16). "My dream is that one day no one will remember that I had anything to do with it."
